On the critical Choquard-Kirchhoff problem on the Heisenberg group

open access: yesAdvances in Nonlinear Analysis, 2022
In this paper, we deal with the following critical Choquard-Kirchhoff problem on the Heisenberg group of the form: M(‖u‖2)(−ΔHu+V(ξ)u)=∫HN∣u(η)∣Qλ∗∣η−1ξ∣λdη∣u∣Qλ∗−2u+μf(ξ,u),M\left(\Vert u{\Vert }^{2})\left(-{\Delta }_{{\mathbb{H}}}u\left+V\left(\xi )u)=\

Analytic height correlation function of rough surfaces derived from light scattering [PDF]

open access: yes, 2016
We derive an analytic expression for the height correlation function of a rough surface based on the inverse wave scattering method of Kirchhoff theory. The expression directly relates the height correlation function to diffuse scattered intensity along ...

The Morse property for functions of Kirchhoff-Routh path type

open access: yesDiscrete & Continuous Dynamical Systems - S, 2019
For a bounded domain $ \subset\mathbb{R}^n$ let $H_ : \times \to\mathbb{R}$ be the regular part of the Dirichlet Green function for the Laplace operator. Given a fixed arbitrary ${\mathcal C}^2$ function $f:{\mathcal D}\to\mathbb{R}$, defined on an open subset ${\mathcal D}\subset\mathbb{R}^{nN}$, and fixed coefficients $ _1,\dots, _N\in\mathbb{R}

Cascadia subduction slab heterogeneity revealed by three‐dimensional receiver function Kirchhoff migration [PDF]

open access: yesGeophysical Research Letters, 2017
AbstractWe present a 3‐D model of upper mantle seismic discontinuity structure below Cascadia using a receiver function Kirchhoff migration method. A careful analysis of the primary and multiple reverberated phases allows imaging of the Juan de Fuca plate dipping below the North American continent. The subducting slab is observed as an eastward dipping

Effective resistances and Kirchhoff index in subdivision networks [PDF]

open access: yes, 2016
We define a subdivision network ¿S of a given network ¿; by inserting a new vertex in every edge, so that each edge is replaced by two new edges with conductances that fulfill electrical conditions on the new network.

The Existence of Nontrivial Solution for a Class of Kirchhoff-Type Equation of General Convolution Nonlinearity without Any Growth Conditions

open access: yesAxioms, 2021
In this paper, we consider the following Kirchhoff-type equation: {u∈H1(RN),−(a+b∫RN|∇u|2dx)Δu+V(x)u=(Iα∗F(u))f(u)+λg(u),inRN, where a>0, b≥0, λ>0, α∈(N−2,N), N≥3, V:RN→R is a potential function and Iα is a Riesz potential of order α∈(N−2,N).

Global well-posedness of Kirchhoff systems [PDF]

open access: yes, 2012
The aim of this paper is to establish the $H^1$ global well-posedness for Kirchhoff systems. The new approach to the construction of solutions is based on the asymptotic integrations for strictly hyperbolic systems with time-dependent coefficients. These

Global Attractors of the Extensible Plate Equations with Nonlinear Damping and Memory

open access: yesJournal of Function Spaces, 2017
We prove in this paper the existence of a global attractor for the plate equations of Kirchhoff type with nonlinear damping and memory using the contraction function method.

General decay for weak viscoelastic Kirchhoff plate equations with delay boundary conditions

open access: yesBoundary Value Problems, 2017
We consider a weak viscoelastic Kirchhoff plate model with time-varying delay in the boundary. By using a suitable energy and Lyapunov function, we obtain a decay rate for the energy, which depends on the behavior of g and α.

Low-frequency sound transmission through rough bubbly air–water interface at the sea surface

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2017
Transmission of a sound generated by a localized point source in the air through a realistic sea surface is studied by the use of the Kirchhoff-Helmholtz integral.
